VEHICLE-WHEEL.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed November 2- 1906. Serial No. 841-728.

To all whom it may concern Be it known that I, EMIL SUTHERLAND, a

citizen of the United States, residing at Hollywood, in the county of Los Angeles and State of California, have invented new and useful Im rovements in Vehicle-Wheels, of which the l llowing is a specification.

The object of my invention is,to provide a wheel for a vehicle which is light, strong and durable which embodies means between the rim or folly of the wheel and the hub thereof to prevent the jar of the rim of the wheel from being transmitted to the hub thereof. I accom lish this object by means of the device d dscribed herein and shown in the accompanying drawings in which:-

Figure 1-is a side elevation of a wheel partly in section embodying my invention. 20. 1

2is an enlarged transverse section ta enon line 22 of Fig. 1.

My device is more particularly ada ted for use in auto vehicles adapted to be driven at a high'rate of speed over rough roads and which are usually rovided with elasticor pneumatic tires to a sorb the jars occasioned thereby.

In the drawings 1 is a solid rubber tire, in lace of whicha pneumatic tire can be used If desired. 2 is the folly thereof on which the rubber tire is mounted. To permit the non-deformable rim of the wheel to be thrown upward suddenly in passing over inequalities in the roadbed I have interposed between the folly and the spokes the carr ing springs 3. The spokes 4 are pivotal y mounted as at 5 in two annular plates 6 for'ming hubs.' The inner ends of the spokes terminate in the bifurcations 7 which carry on their 'outer ends the bearing wrists 5 which are journaled in the hub plates 6 as before stated. Projecting inwardly from either end of the bifurcations 7 is a project'- ing lug 8 provided with a socket or eye 9 adapted to slidingly receive one end of a flat compensating spring 10. The other end of these springs is keyed or otherwise secured intransverse openings 11 in the end of the bifurcations 7. By. means of these compensating springs projecting. one end into and the other end secured in the inner end of the spokes I provide means to hold the spokes in a position nearly radial to the hub ably secured in two p as shown in Fig. 1.

.Each of the carrying springs 3 is detachaces as at 12 and 13 at its outer end to the rim or .felly. The inner ends of these s rings are pivotall attached to one end of the'connecting lin 14 as at 15, this conneo'tin link is swingin 1y mounted on and close to t e inner end of 516 spoke as at 16, thereby workably connecting e inner end of the carrying spring to the s oke and conneotin the rim and hub of the wheel together. hese carrying springs carry a proximately in their center, securely a ed thereto, a bracket 17 to which the outer end of each spoke is fpivoted by the pintle bolt 18. The hub o the wheel is mounted on the axle 19 and is provided with the ball bearings of ordinary construction.

Thus it will be seen that I have rovided a wheel in which that art of the w eel connecting the hub with t e rim is so construct ed as to permit the rim of the wheel to have a rapid up and down movement'without necessarily affecting the hub by the jars which are occasioned b the inequalities of the surface of the roadbed when the wheel is being driven rapidly over the same. The fiat configuration of these springs, while the i are resilient will impart great rigidity so ar as any lateral movement of the wheel is concerned and rigidly hold the wheel in proper osition at right angles to the axle on whic the same is mounted and will at the same time afford the necessarv resiliency to permit the rim of the wheel to bob u and down and relieve all parts of the vehic e ex* cept the rim of the ars occasioned by inequalities inthe surface of the roadbed while the wheel is bein rapidly passed thereover.

To provide adr 'tional means of preventing contacting with the ends of the spokes I have,

provided the elastic bumpers 20 against which the carrying s rings will contact providing a cushion W hich will prevent too abrupt a jar.

Having described my invention what I claim as new and desire to secure by Letters Patent is:-

1. A vehicle wheel having a non-deformable rim; carrying springs interposed between the spokes and the rim and workably connecting the same together; annular plates forming hubs and carrying the spokes pivotally connected thereon; compensating springs extending from the inner end of one spoke to the inner end of another spoke, t c said springs being keyed to one spoke and having a sliding fitin a socket in another spoke.

2. In a vehicle wheel, a plurality of spokes being pivotally secured at their inner ends and carrying ontheir outer ends carrying springs and connected together at their inner ends with ,co ensatlng springs.

3. In a vehicle w eel of the character,

herein described, spokes carrying 'on their outer ends carrying springs, the sald carrying springs being detachably secured to the rim at one end and pivotally connected to a link at the other end, the said link beingpivotally secured to the inner end of the spoke; a

bracket mounted approximately on the center of the carrying springs and pivotally connected withthe outer end of the spokes.

4. A wheel of the character-herein described, having two annular plates surrounding and forming part ofthe hub of the wheel,

' the said plates having holesftherein for the rece tion of bearing-wrists on the inner end of t e s okes, -'in combination with spokes having wrists thereon; and compensat springs secured to the inner-ends of the spo res, each spring being rigidly secured at one end to the inner endof the spoke and the other end of the spring having a sliding engagement with the inner end of another spoke, and means to workably connect the rim of the wheel with the spokes. v

5. In a Ivehicle wheel of the character herein described, the herein described spoke,

ifurcated inner ends with'bearing' Witnesses:

having on its outer ends means to pivotally secure the same to a carryin spring and having on the inner end thereo a socket for the sliding reception of one end of a compensating sprmg'and having keyed in said inner end an end of another compensating spring.

6. In a wheel of the character herein described, having the inner ends of the spokes.

to the rim at its outer end and its inner end pivotally connected near the center of the spring to the outer end of the spoke and havmg a swinging connection at its inner end with the inner end oit the spoke; spokes ivotally mounted annular plates on the ub and carrying asteadying spring on the inner end of the spoke and havlng a sliding engagement with anend of another steadying spring.

" n witness that I claim the foregoing I have hereunto subscribed my name this 24thday of October, 1906.
